CORN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 325,190, dated August 25,1885.

Application filed October 24, 1884.

To aZZ whom it may concern.-

Be it known that I, CHARLES WILLIAM- SON, a citizen of the United States, residing at (Jrawfordsville, in the county of Mont- 5 gomery and State of Indiana, have invented I i tate with the shaft D they are permitted to 55 a new and useful GornHarvestcr, of which the following is a specification.

My invention relates to corn-harvesters; and the objects of my invention are to proro vide a strong and simple machine which will gather the ears of corn from the stalks, tear off the husks from the ears, and collect the ears in a box, which can be emptied at the will of the operator. 1 by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a front view of my corn-harvcster; Fig. 2, a top view of the same; Fig. 3, a side view of the same; Fig. 4, a vertical 2o cross-section through the machine on lines mm on Figs. 2 and 3; Fig. 5, a longitudinal vertical section on lines 3 y on Figs 1, 2, and 4; Fig. 6, alongitudinal vertical section on lines 2 e on Figs. 1, 2, and 4,.

Similarletters refer to similar parts throughout the several views.

A is an arched frame or axle, the two ends of which form the axle-spindles a and a for the wheels W and W, that support the machine.

()n the spindle a is loosely mounted the compound sprocket and gear wheel B, said wheel being provided with sprockets 011 its outer rim and with an internal gear.

5 the cogs of said wheel B engages the pinion f, which is keyed to the end of the horizontal shaft F, to the other end of which is keyed the bevel gear-wheel The shaft F'operates in a bearing or sleeve, a, which forms part of 40 or is rigidly bolted to the arch A. The vertical bevel gear-wheel f operates the horizon- I attain these objects Into tal bevel geanwheel h and the vertical shaft H, to which said wheel it is secured.

The

shaft H is supported by and revolves in a boxmeans to secure the lever L, the arch A, and

5 ing formed in or firmly secured to the arch A.

Keyed to the shaft H, above the arch A, is the circular saw or cutter It. At each side of the saw or cutter 71. from the arch A rise the standards a and (B, which at their upper g l ends form bearings for the horizontal shaft D.

(No model.)

To one end of said shaft 1) is firmly secured the sprocket-wheel G. The rasp disks d dare keyed to the shaft D between the bearings a and a in such a manner that while they ro 5 These springs hold the raspdisks d d in place on the shaft D, permitting them to move laterally 011 said shaft. The disks (2 cl are provided with protruding teeth on each surface hence I call them raspdisks. Slipped onto the two rods E E are the rasp-plates e c e,

one being located in the center between the disks d d, and one off to each side at equal distances from said disks (1 (I. These plates 0 e e are separated by the spiral springs m m, wound around the rods E and E. The plates are provided on each surface with protruding teeth, the same as the disks d (I. The brackets a a being firmly secured to the standards a (L or to the arch A, form the supports for the rods E and E. lt-igidly fastened to the arch A and in front of the same, extending down to near the ground, are the fingers S S S. Pivoted to an extension of the spindle a,

' under the arch A, is the arm G, to the fore end of which is bolted the tongue T of the ma- 8o chine. The lever L, having its fulcrum-point on the said arm G, and being connected with the arch A by a pitmanrod, l, is used to raise or lower the lingers S S S from or to the ground. The seat V of the driver is braced 8 onto the tongue T.

By pulling the lever L toward the rear the rod P pushes the arch A back and down, lifting the ends of the fingers S S S above the ground, the arch pivoting and turning on its spindles a. and a in the hubs of the wheels and \V.

The pawl N and the ratchet g form the the fingers S S S in any desired position. The 5 pawl l\ slides up and down alongside of the leverL and engages with the notches g g, which are worked in a semicircle on the upper similar locking device for the lever L can be' used. Pivoted between and to the two brackets a a that are secured to and extend back from-the arch A, is the box I, into which the.

ears of corn are collected. To enable the oper-' ator to dump this box I and empty its contents on any desired spot, the dumping device K is used. K is atreadie or foot-lever pivoted to the tongue T. This treadle Kis connected with the box I by a rod, is, the said rod 70 being pivoted to the foot-lever K and to the side of the box I at such points that a downward pressure on the lever K will depress the fore end of the box I and dump its contents.

The machine operates as follows When the corn-harvester is to be transported to the field, the fingers S S are raised above the ground by the aid of the lever L and secured in position by the locking device N g n l l.

The machine travels on the wheels W and V. Arrived in the field,the machine is brought into position with the fingers S S S facing toward the end of a row of cornstalks. The whr el \V is connected with the gear and sprocket-wheel B by the slipbolt in, or any other device by which the two wheels can be locked together, so that the wheel W becomes the driving-wheel of the whole mechanism. The team is then started, the cornstalks are guided by the fingers S S S, the ears of corn are pulled up toward and between the raspplates 6 c c and the disks (1 d, and are cut from the stalks by the rotating saw or cutter h, the rotating rasp-disks d 6?, taking hold of the ears, press the same against the stationary plates 6 e e, and, by forcing the ears backward and brushing them against the plates 0 e e, strip away the husks. The ears drop then at the rear into the box I. WVith the driving-wheel Vi. rotates the combined sprocket and gear wheel B. The sprockets of the wheel B operate by a chain,lt, the sprocket-wheel O and the horizontal shaft D, and with the shaft 1) rotate the husking-disks d d.

To prevent the clogging or twisting of the husking wheels and plates, the said wheels and plates are mounted on their respective shafts and rods with springs between their hubs, so that they will give laterally.

The pinion f is driven by engagement with the internal gear of the wheel B. The shaft F and the bevel gear-wheel f rotate with the pinion f. Thebevel gear-wheelf engages with the bevel gear-wheel h and operates the shaft H and the circular saw or cutter h.

Having thus described the construction and operat on of my corn-harvester, what I claim, and desire to secure by Letters Patent, is-
